Sony Xperia Z5 premium. I had an unlocked bootloader and custom ROM. I was going to resell the phone, so I used flashtool to re-lock the bootloader and flashed a stock ROM. E6853, flashed correct model specific .ftf file. So...now I have a working stock phone. I do not have access to the bootloader, or recovery. When i adb reboot bootloader, it goes to a black screen with a blue LED. If I volume down when plugging in USB, it does the same thing. I am not rooted, so I can't flash from within the OS. I think I relocked the bootloader successfully, but can't unlock it now, because I can't access the fastboot. Does anyone have any ideas?

i want boot repair file
Can you boot into flash mode or fastboot?
i have same problem i flashed cwm zip through twrp then booted into cwm and done all wipes ie system,data,cache,davlik and then phone went off now nothing att all happens not even charging?
It won't boot if you've wiped the system and data in recovery there's nothing left to boot up you'll need to flash ftf via flashtool and start from the beginning
I've got the same problem, i built AOSP 5.1 and flashed it via fastboot (boot.img, system.img & userdata.img) and now the screen doesn't power on (bootloader is unlocked). I also can't get into fastboot/recovery. What should i do now?
This is the first time i'm trying to put a custom ROM on a sony device.
Thanks in advance!

Did you update your bootloader? before flashing the custom rom.

Update the bootloader?
I did it the same way i did it on my oneplus one, which is just oem unlock.
On oneplus one this updating isn't needed, how do i do it?
A Xperia isn't a opo, it's sonys recovery partition you'll need to flash the updated bootloader through Emma sonys version of flashtool for unlocked bootloader devices
Whenever I try unlock bootloader bug out FAILED (remote: Command did not allowed).
I have Bootloader unlock allowed.
I tried in CMD - Fastboot and Flashtoo and out this same problem.
When I tried twice unlock bootloader I get OKAY and I try turn on my phone, I walk in bootloop.
Where is problem?
Hi! So actually you did unlocked your bootloader (as i understand), and when you turn on your device after the unlock you go into bootloop. This is something normal. You need to flash the stock .ftf with flashtool (i recommend you to use old versions like 0.9.11.0). Have a look here:
http://forum.xda-developers.com/xperia-l/help/bootloop-unlocking-bootloader-t2675892 ! Good luck!
What firmware version did you flashed. I have flashed firmware for c2104 and i got this bootloop. Make sure you flash the propper firmware verison for your device.

Maybe you have to choose between root and locked BL? Read this:

I can't say more because I never tried to lock again my XA (useless?).
Hey guys, i have a problem, my Bootloader is locked and i can't access my recovery, and there is no rom installed, what should i do now? i can't access Developer options to Allow OEM unlock because there is no OS.
am i screwed? or there is something i can do?

Did you ever enable developer options and allow USB debugging? If so, and you can connect to ADB on a PC, you can flash stock firmware back onto the phone.
or try this:
As I didn't have USB debugging enabled I couldn't connect to the phone via ADB, but if you put it into recovery mode you can use Fastboot. Hold down the power key to turn the device off and turn it on while holding down Vol Down to load up recovery mode.

However, with locked bootloader there is no room for error in flashing firmware via ADB or you will brick the phone. You have to flash the correct firmware exactly for your phone, with the same level of bootloader you already have or newer. You can't flash Mexico over Brazil or Lollipop over Marshmallow. Has to be exactly what was made for your phone, either what you already had or newer (if it exists).
What OS was installed before?
But WHY is there no ROM installed? What did you do?
The OS installed before was the most recent Stock MM Brazil, i installed the stock rom, it worked, then i wanted to go back to stock recovery, it it worked too, then i wanted to locked my bootloader, i locked, after that i couldn't enter recovery, neither boot to OS.

You wanted to re-lock your bootloader? Unlocked bootloader = God mode.
Did you ever have TWRP? You said you wanted to go back to "stock recovery" (not sure why, it's mostly useless compared to TWRP custom recovery.)
I'm not sure why re-locking the bootloader would wipe the OS...
But you can boot to the bootloader screen using the volume and power button and re-flash the stock firmware, using ADB. Here's the link to the newest Brazil Marshmallow for XT1225:

This guy below got out of a jam because he had an unlocked bootloader, which is very forgiving. Locked bootloader is harder.

Yeah, i don't know what happened either, why the **** did my OS got Wiped?

You have to boot to the bootloader screen manually, using the volume + power button trick.
Once on the bootloader screen, when you plug you phone into a PC with ADB installed, it should recognize it.
Then, flash the full stock firmware, from the link above. It's Brazil Marshmallow firmware with December 2016 Security Update. I don't know of any newer right now. You have Brazil XT1225, so that Brazil firmware is compatible with your phone.
But with locked bootloader you have to flash exact same version or newer made for your phone, and you have to enter the commands correctly or you may brick your phone. (When I flashed from Puerto Rico Kitkat to India Lollipop, I messed up. But since my bootloader was unlocked, I just reflashed again, when I realized my mistake.)
If you are not sure of the steps, google Motorola firmware ADB. Here's a couple of excellent tutorials:
How to Manually Official Firmware on any Motorola Device
https://forum.xda-developers.com/dr...force-how-to-manually-flash-official-t3282077
I use this one above. IGNORE where it says you need an unlocked bootloader, because he's talking about cross-region flashing which you are NOT doing. You are flashing your own region firmware.
This one below is by rootjunky and he while he also discusses RSDLite, later in the article he says ADB/fastboot are best as RSDLite can stall.
Motorola Firmware Restore Plus Unbrick
http://www.rootjunky.com/motorola-firmware-restore/
If you get your phone running again, I suggest you unlock the bootloader. There are ways to hide an unlocked bootloader (like Magisk), if that's why you locked it back... But an unlocked bootloader + root makes it YOUR phone and much easier to recover from disasters.
Thanks a lot Chazz, it worked, thanks for the help, really appreciate it, thanks for all the useful tips too.
Just as the title says...
I have Xperia Z5 SOV32
It has Bootloader Unlock Allowed: NO, but somehow I can go into fastboot mode
Some people said that they cannot get into fastboot mode since they can't unlock their bootloader
If I continued to flash a stock (or a region customized stock) FTF, will it brick the device?
Thanks!
No, its normal. You can always boot into fastboot, even if you cant unlock it. Stock rom is always flashed over flashmode so you can flash whatever you want
Thanks, just to make sure first before doing anything to it, and indeed it works flawlessly
